Out Of 100000 tons of steel and
iron manufactured annually at the
Krupp works the greater portion is re-
quired for peaceful purposes; especially

that the number of workmen employed
in the cast-steel works amounts to H.
211, and those employed in mines and
and forges to 1894, being total of
19,605. To these we may reckon the
families of the employees, numbering
45,776, thus showing that 65,SS1 per-.
sons were at that time dependent on
the Krupp establishment for a liveli-

new invention dispenses entirely with
the human lungs, and injects the air
into molten glass by an air-pump not
unlike an ordinary syringe in shape
and action. This is fastened to the Or
dinary blow-pipc and makes little diff
ference to the workman in handling
